The thickness of the layer is between 100 and 160 [micro]m, being the height (flame-substratum base) of 15 cm with fuel flame, the best condition to achieve a thicker layer in the same number of turns, likewise for the neutral flame at 12 cm.

In images of 18 cm can be observed that with the fuel flame can be obtained a thicker layer than with the neutral flame.

The images of the projections made at a 12 cm distance, show a great difference between both atmospheres, because for the neutral flame the disunion between splats and porosity is observed in much of the coating layer, besides of horizontal cracks or disunion between the splats, this due to the elevated projection temperature, because for shorter distances there is more heating (Restrepo, et al.

As it is observed in the Table 5, the adhesion values are higher for the fuel flame, this can be attributed to that this type of atmosphere reaches an approximate temperature of 3200[degrees]C, causing a higher energy than the neutral flame (approx.

It was found that the higher roughness values of the coatings, both with neutral flame as with the fuel flame, occur at 15 cm and the values with less roughness in both cases are in distances of 18 cm.
